Alexander Armstrong shared a picture on his Twitter of him with Matt Smith on set for this years Christmas special. It shows that the Doctor will be back to wearing his classic tweed jacket and not the long coat he has been wearing recently.

The World War II based episode also guest stars Claire Skinner, Bill Bailey and Arabella Wei, and features appearances from Karen Gillan and Arthur Darvill!. See more pictures from the set of the Christmas special in our older post here and here.
